Problems solved by technology

When completely occluded, there is less hemorrhage during liver surgery, but liver function is affected; when fully open, the blood supply to the liver is rich, the amount of bleeding is large, and there are many intraoperative and postoperative complications; The closing time is short, which affects the operation process, and on the other hand, causes "ischemia-reperfusion" injury to the liver

Abstract

The invention provides a quantitative blood stream limiting device which comprises a blood stream detection device, a blood stream limiting device and a control system; and the blood stream detection device and the blood stream limiting device are respectively connected with the control system. The blood stream detection device is an ultrasonic Doppler probe; the blood stream limiting device is an elastic circular sac filled with fluid; and the flow of the fluid in the ultrasonic Doppler probe and the elastic circular sac are controlled by the control system. Due to the adoption of the quantitative blood stream limiting device, the blood stream of organs can be limited quantitatively and precisely, so that the impact on the functions of the organs is minimized while the blood loss in a surgery is minimized.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a device for quantitatively restricting the blood flow of the vascular system. Background technique [0002] In modern liver surgery, restricting blood flow into and out of the liver and reducing intraoperative bleeding have become the basis of hepatectomy. However, in the literature at home and abroad, in the method of hepatic blood flow restriction, which is one of the most important techniques in liver resection, whether it is the most classic and widely used hepatic pedicle blood flow occlusion method or the whole liver blood flow occlusion method , hemihepatic blood flow occlusion method, hemihepatic blood flow occlusion method with preserved arterial blood supply, hepatic blood flow occlusion method with hepatic artery intermittently blocked portal vein, hepatic blood flow occlusion method through Glisson sheath system in different regions Methods such as cutting method a...
